Edgerton, Germeshausen, and Grier, Inc., or EG&G, got its start as a U.S. national defense contractor. EG&G provided defense management solutions and technical solutions. It has played a part in several important national events, including World War II, nuclear tests with the Atomic Energy Commission, and high-tech military equipment testing. EG&G is a manufacturer of test equipment such as sensors, security systems, amplifiers, preamplifiers, imaging products, and microwave and electronic components. URS officially purchased the EG&G brand 2002. Now, consumers turn to sites such as ValueTronics.com to find the used and refurbished EG&G testing products they want after their discontinuation.
